7.3 HDR – Perceptual Quantizer (PQ)
About PQ
Perceptual Quan tizer (PQ) is a, electro-optical transfer function (EOTF ) that allows for the display of High Dynamic R ange (HDR)
content with a luminance level of u p to 10 000 cd/m² and can be used with the Rec. 2020 color space.
If your provided HDR content has been m astered w ith Pe rceptual Quantzier (e.g. Dolby Vision or HDR10) , you can adapt the
luminance on screen to adapt to the provided content.
For op timal d isplay of HDR content, this is just o ne value that will influence the projected image. When enter-
ing the desired screen luminance, take into accou nt the distance of the pro jector to t he screen and the q uality
of the scree n used.
